Williams, Office of High Energy Physics, Office of Science, Department of Energy Stanley Wojcicki, Department of Physics, Stanford University About 60 others were present in the course of the meeting. Thursday, May 29, 2008 Morning Session The meeting was called to order at 8:59 a.m. Chairman Melvyn Shochet asked Dennis Kovar to give a status report from the DOE Office of High-Energy Physics (OHEP). The FY08 program had a reduction from the request. It has been a productive program nonetheless. Tevatron is running well with the Collider Detector at Fermilab (CDF) and D0, the Main Injector Neutrino Oscillation Search (MINOS), and MiniBooNE. The B-Factory completed a successful 4-month run. The Large Hadron Collider (LHC) and the A Toroidal LHC ApparatuS (ATLAS) and Compact Muon Spectrometer (CMS) detectors are proceeding on schedule. The Gamma Ray Large Area Space Telescope (GLAST) is set to launch in June. And a number of projects are under way: Main Injector Experiment ν-A (MINERvA), Tokai-to-Kamioka (T2K), Daya Bay, the 200-kg Enriched Xenon Observatory (EXO-200), Dark Energy Survey (DES), and Second-Generation Cryogenic Dark Matter Search (CDMS-II). DOE and the National Aeronautics and Space Administration (NASA) are planning to proceed on the Joint Dark-Energy Mission (JDEM). An agreement has been reached with the National Science Foundation (NSF) on the LHC Phase I upgrade. Funds have been increased for Outstanding Junior Investigator awards. A dark-energy R&D solicitation has been issued. Significant impacts of the budget include the curtailing of the B-Factory run; the reduction of staff at Fermilab; the stopping of the NuMI Off-Axis ve Appearance (NOvA) experiment; and reducing support for the International Linear Collider (ILC) and superconducting radiofrequency (rf) R&D to a minimal level. An FY08 supplemental bill was passed by the Senate that gives an additional $45 million to HEP, but there has been no action by the House. A U.S.-Japan annual review meeting will be held at Brookhaven National Laboratory (BNL). There will be a Fermilab review and an ILC review. A review of the Stanford Linear Accelerator Center (SLAC) will be held in July. National-laboratory theory and accelerator reviews will be held in July, also. The FY09 budget request is $150 million over of the FY08 request. A 6-month continuing resolution (CR) is expected. Some projects will be delayed (e.g., the Advanced Plasma Accelerator Program). There will be reductions at the national 2 laboratories. If the CR is too long in duration, the Department will not be able to go forward with NOvA. FY09 will be pivotal. The FY10 budget request will be submitted to a new administration from whom guidance will be required. Five new positions in the Office are being advertised. Five Intergovernmental Personnel Act staffers (IPAs) are coming in, and three are leaving. A gift to Fermilab was announced a few days before this meeting. The rolling furloughs have been stopped. Cahn asked when the funding opportunity announcement (FOA) for JDEM would come out. Kovar replied, in 2008. Cushman asked if Panel members can call their House members about the supplemental funding. Shochet replied, yes. Eno asked when the Particle Physics Project Prioritization Panel (P5) report would have an effect on the budget. Kovar responded that it will be looked at for the FY09 request. Bagger asked if it were needed now or a month from now. Kovar replied that the report that HEPAP is happy with should come out as soon as possible. Joseph Dehmer was asked to comment on the status of the NSF Division of Physics. The P5 report is vital and urgent to adjust for developments during the past 18 months. The Division went from an 18% to a 1% increase overnight. $3 million were taken out of the facilities. The Physics Frontier Center program was cut 5%. However, assistance to Deep Underground Science and Engineering Laboratory (DUSEL) has been maintained. The Advanced Laser Interferometer Gravitational Wave Observatory (Advanced LIGO) was approved; the project will start soon. At the energy frontier, support for Tevatron experiments was cut, the Large Hadron Collider was not, and R&D for a future collider was funded at the Cornell Electron Storage Ring (CESR) Test Accelerator (TA). DUSEL has had a third solicitation and award, with a fourth solicitation nearing the end of its approval process. At the cosmic frontier, U.S. efforts are providing global leadership through CDMS, Xenon, IceCube, Auger, Borexino, Advanced LIGO, Veritas, etc. DOE and NSF are poised to respond coherently to advice from P5 and HEPAP. Joseph Kroll asked to present information about the upcoming International Conference on High Energy Physics, July 30–August 5. 900 abstracts have been submitted for parallel sessions followed by three days of plenary sessions. Registration was urged. The final program will be available in a couple of weeks. Visas for foreign nationals may be a problem. Charles Baltay was asked to present the report from P5. At the November meeting of HEPAP, the P5 committee was charged to develop a 10-year plan for U.S. particle physics under various DOE funding scenarios: A Constant effort at the FY2008 level ($688 million) B Constant effort at the FY2007 level ($752 million) C Doubling of budget over 10 years starting with FY07 D Additional funding above the previous level, associated with specific activities needed to mount a leadership program. The Subpanel was also briefed on the status of NSF fiscal planning. The plan described here assumes approval of the DUSEL Major Research Equipment and Facilities Construction (MREFC) proposal, and continued funding of the NSF University Program 3 and LHC operations. Annual budgetary amounts were calculated for each scenario and year. The Subpanel was broadly constituted. A webpage was set up for community participation. Meetings were held at Fermilab, SLAC, and BNL. The six laboratory directors were supportive of the P5 process. The National Research Council’s Revealing the Hidden Nature of Space and Time (the EPP2010 report) and earlier P5 reports have discussed the outlook for the field of particle physics in the United States. The scientific priorities have not changed since those reports appeared, but the context for the scientific opportunities they describe has. Particle physics in the United States is in transition: Two of the three high-energy physics colliders in the United States have now permanently ceased operation. The third, Fermilab’s Tevatron, will turn off in the next few years. The energy frontier, defined for decades by Fermilab’s Tevatron, will move to Europe when Conseil Européen pour la Recherche Nucléaire’s (CERN’s) LHC begins operating. American high-energy physicists have played a leadership role in developing and building the LHC program, and they constitute a significant fraction of the LHC collaborations. About half of all U.S. particle physicists participate in LHC experiments. The U.S. high-energy physics program faces serious fiscal challenges that are changing the particle-physics landscape even as this transition occurs. The large cost estimate for the ILC, a centerpiece of previous plans, has delayed plans for a possible construction start and has led the particle physics community to take a fresh look at the scientific opportunities in the decade ahead. The severe funding reduction in the Omnibus Bill of December 2007 stopped work on several projects and had damaging impacts for the entire field. The present P5 Subpanel has developed a strategic plan that takes these new realities into account. There is a lot of excitement in particle physics. It has been very successful in creating a major synthesis, the Standard Model, that explains to a high accuracy almost all experimental observations so far. However recent results show that there is new physics beyond the Standard Model.

  • Lepton-Number Violation in B Decays at BABAR
    DPF2013-122 June 20, 2021 Lepton-number violation in B decays at BABAR Eugenia Maria Teresa Irene Puccio1 Department of Physics Stanford University, Stanford, CA, U.S.A. We present results of searches for lepton-number and, in some cases also baryon-number, violation in B decays using the full BABAR dataset of 471 million BB pairs. PRESENTED AT arXiv:1310.0876v1 [hep-ex] 3 Oct 2013 DPF 2013 The Meeting of the American Physical Society Division of Particles and Fields Santa Cruz, California, August 13{17, 2013 1On behalf of the BABAR Collaboration 1 Introduction The observation of neutrino oscillations suggests that lepton flavour is not a con- served quantity. If neutrinos have mass, then the neutrino and antineutrino can be the same particle and processes involving lepton-number violation become possible. The most sensitive searches for lepton-number violation are currently found in neutri- noless double-beta decays [1]. However the nuclear environment of this type of search makes it difficult to extract the neutrino mass scale. Processes involving mesons de- caying to lepton-number violating final states have been suggested as an alternative to the neutrinoless double-beta decay searches. Figure 1 shows an example Feynman diagram for a B decay to a lepton-number violating final state via the exchange of an s-channel Majorana neutrino. It is however expected that these decays have ex- tremely small unobservable probabilities and therefore the observation of a significant signal would be a clear sign of New Physics. Figure 1: Example diagram of a process with ∆L = 2 due to the exchange of a Majorana neutrino[2].
